Tag colours in MindManager 16

The facility to add colours to text tags in MindManager 16 is quite useful but I'd like to suggest two improvements:

An optional facility to sync tag colours with Outlook category colours. MM tag colours seem to be completely independent of Outlook ones. This does have the advantage that MindManager is able to offer a much greater range of tag colours than Outlook, but it would be great if there was an option to adopt and maintain Outlook category colours when tasks and appointments are synced between the two programs. I'm pleased though that MM has retained the ability for topics themselves to retain Outlook category colours after syncing.

The capacity to group and filter topics based on their tag colours. It would be useful also if tags with the same colour could be grouped in the Marker Index and if tag colours could be used in the power filter. This would provide the ability to have and search and filter on simple hierarchies or groupings of tags based on their colours.
